HTML HyperText Markup Language is a tool to create web pages.

Consist of different elements that combines together to produce a web page. Each element of the page is represented by markups known as tags.

each tag represents different parts of the page such as head, body, tables, forms, heading and many more.

a HTML is processed by a browser to produce its output, the web page. Browsers are such as Firefox, Internet Explorer, Chrome and Safari. HTML tags tells these browser how to render its output, or how to display different part of the page.

Drawing Simple Pie Chart

Image
To draw pie chart with 5 sectors. The program calculates the total of all the input given by user and find the angle in degrees to draw each sectors. When the program first loads, chart based on default values is painted by the program. User can edit the values in the text field and presses draw button to redraw the chart. Each time the draw button is pressed, new set of angle is calculated and repainted. I have attached the the sources for this program. It is simple and needs upgrades. Pie.java This class executed the program and initializes the components JTextField and JPanel to draw the chart. package coolApp.graphics; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Pie { JTextField a,b,c,d,e; JButton btnDraw; double total; JPanel contentPane; Pie(){ JFrame frame = new JFrame("Pie - CoolApps"); frame.setSize(500,500); contentPane = new JPanel(); contentPane.setLayout(new BorderLayout()); frame

Imports System.Data.SqlClient Step 1 Create a sql connection object. This is to make connection to object. Dim conn As New SqlConnection() Step 2 Set the connection string to the sqlconnection object: conn.ConnectionString = connStr Road block The variable connStr is a connection string. Connection object need connection string to make connection to database. It has information like who providing the database, the name of the database and some security information. Dim connStr As String = "Data Source = ServerInstanceName;Initial Catalog=testDB;Integrated Security=True" Let's break down the connection string into the three main components.

VB.net

a quick and convenient way to build a window based application. basically there is two main components in VB, the design view where we place the controls on a window form. then we have the code view where we write implementation for each controls on the form. Typically the control implementation or procedures are executed when certain events happens to the controls. Events like mouse click, or value change on text box, form load, form close and so on. After working with programming language like C, C++ and Java, getting use to VB is a bit challenging. its because first of all, VB don't use curly bracket to specify code blocks, and the statements don't end with semicolon. variable declaration for example is written as dim age As Integer in C, C++ and Java it written int age; in VB, variable declaration start with dim keyword, it means dimension and the functions are written as Function addNumber(ByVal num1 As Integer, ByVal num2 As Integer) As Integer addNumber
